Silver plating companies use electrochemical processes to apply a thin layer of the precious metal over another base material, providing many advantages for your product.
Place a 9-volt battery next to the basin containing an electrolytic solution and connect its positive terminal with a piece of silver for use as the anode in this process.
Preparing the Substrate
At the outset of silver plating companies, inspection is the initial step to ensuring an effective finish. Any imperfections must be identified and addressed before beginning the electroplating process.
Next, the substrate is submerged in an electrolytic solution composed of silver nitrate. A wire connected to a battery connects directly with the piece of silver to be plated (known as an anode) as an alligator clip holds onto its piece before slowly being submerged into solution.
Electroplating silver requires plating ions from silver solution onto an anode, coating it with metal. Unfortunately, all of the same issues that arise during any electroplating process – adhesion loss and dull spots can still arise when electroplating with silver; these issues could arise from various sources, including inadequate temperature conditions in the solution or interruption in the flow of electric current.
Plating the Substrate
Rack plating involves fastening the metal substrate to a rack and submersing it in an electrolytic solution containing silver ions, before running an electrical current through this solution and depositing silver onto its surface to form the desired metal – in this instance silver.
Silver is an adaptable metal that can provide matte, bright, or semi-bright finishes to products. Additionally, its solderability, electrical conductivity, and antimicrobial properties make it ideal for medical devices, including catheters and tubing as well as obturators and cannulas that come into contact with tissue that’s more susceptible to infections.
Silver has the capability of significantly decreasing power waste consumption by up to 90% in many electronic conductor applications, helping extend battery life for portable, handheld, and wearable medical devices. Furthermore, its anticorrosive properties prevent corrosion on polymer components used in catheters, obturators, and cannulas.
Cleaning the Substrate
To ensure the plating process works successfully, there must be a tight bond between your base metal and its new metal coating. For this to occur, however, all debris must first be completely clean of grease, dirt, paint or rust flaking off, waxes, or chemicals which could interfere with adhesion between surfaces preventing proper adhesion between them and adhesion between two surfaces that is integral for the plating process.
To prevent this from occurring, your base material’s surface must be meticulously cleaned. A multi-step cleaning sequence using various cleaning methods such as acid cleaning can be utilized; mechanical or laser methods offer more precision in this regard. The initial step involves acid removal from oxide layers on substrate surfaces using mechanical or laser methods respectively.
Alkaline cleaning is the second step of a multi-step cleaning sequence, in which an alkaline solution is used to rinse your substrate or component thoroughly clean of grease, rust, or particles that remain. This step may be performed through spraying or immersion cleaning.
Finishing the Plating
Silver plating services can be an intricate process to navigate for companies new to this form of work. Issues like adhesion loss, dull spots, and incomplete coverage could occur if your technicians lack experience in managing it properly.
Avoid these problems by ensuring your metal parts are in top shape before beginning production. Pre-treatment allows you to address cold shuts or other imperfections that might cause poor results.
Once your item has been coated in silver plating aluminum, it can be finished off in various ways. For decorative products such as furniture or decor items, this may involve either a bright or matte finish – this adds elegance while improving texture; often desired by consumers seeking luxurious pieces. Alternatively, silver is often specified for its antimicrobial and tissue-sticking properties for more practical uses such as electrosurgical handheld devices and energy therapy equipment.
